[Lower urinary tract dysfunction and herniated disk]

Lower urinary tract dysfunction related to herniated disk can raise complex diagnostic and management problems. This article reviews the two main clinical situations encountered: documented lower urinary tract dysfunction in a context of cauda equina syndrome secondary to herniated disk and lower urinary tract dysfunction representing the only clinical sign of herniated disk with no other alteration of the neurological examination. Regardless of the neurological signs, urodynamic assessment is essential to characterize any lower urinary tract dysfunction and to determine the modalities of long-term surveillance.
